Application October 18, 1934, Serial No. 748.830

Ellis invention relates to a bottle and particularly to an arrangement for sealing the bottle with a simple and efiective seal which-cannot be replaced once :it has beenremoved.

object 10f thelinvention :is to provide ca sealing means which formed in the neck of the bottle and permanently secured therein, either before or after :filling the bottle.

Another object is to provide a sealing means which man berseen'rea-dily in the neck of the bottle, so that any change in :its condition .canbe noted.-

Another object is to provide a glass sealing means :in a glass bottle such that :the contents of the bottle may come in contact only with glass.

.A still further object is to provide certain im- ;provements in the form, construction, arrangement, and material whereby the above named :and other objects may effectively :be attained.

A practicalzembodiment of the invention is-represented in the accompanying drawing, in which Fig. 1 representsin vertical section, the neckof a :bottle' with .a sealing bulb and tube ready :to be blown into sealing-position;

Fig. 8 represents, in vertical section, a detail of another modified arrangement for securing a sealing means in the neck of a bottle.

Referring to the drawing, the bottle and its seal may conveniently be described by setting forth the steps of one method *whichmay be advantageously used in its manufacture. A bottle I having a neck 2 is molded so as *to form an inwardly projecting shoulder 3 at or near the base of the neck. The inner surface of the neck immediately above the shoulder 3 will normally assume asomewhat concave shape, as shown at t, and this concavity may be increased-or controlled as desired ina manner we'll known-to those skilled in the bottle making art.

'9 Claims; (Cl. 215--32) While the bottle isstill hot and slightly plastic, a glass :tube .5 having its lower end partially blown :in the form of abulb 6 is introduced into the neck 2 :of the bottle, to approximately the distance shown in Fig. 1; the blowing of the bulb 6 is then continued until it reaches the position shown in Fig. 2, wherein the :bulb is intimately engaged with the neck of the bottle along the concave portion @l thereof. This engagement should be effected at a sufficiently high temperature so that the bulb 6 will actually fuse to the neck of the bottle.

Preferably before the bulb '6 has entirely lost its plastic condition-a piercingtool of any suitable character is introduced through the tube 5 in order to puncture the bottomof the bulb 6, forming an opening 1, as shown in Fig. 3. The bottle may then be finished in any usual manner, as by cooling, annealing, etc., up to the point where it is ready to be filled. It will be understood that the tube 5 is open at its top, as shown in Figs. 1 and 2, and the bulb '6 has the opening I in its bottom, 'hence the contents of the bottle may readily be introduced therein through the tube and bulb.

When the bottle has been filled as just described, fusing heat is applied to the tube 5 at a point slightly above the top of the bottle neck and the tube is thus sealed closed, as shown at 8, in Fig. 3. Either before or after filling and sealing the bottle, a diamond tool or the like is introduced into the neck of the bottle and a groove 9 is out completely around the outer surface of the tube 5 at or near its lower end. A protective metal cap or reclosure Ill, arranged to project beyond the sealed end 8 of the tube, is provided, and the bottle is then complete and ready for shipment and sale.

When it is desired to remove the contents of the bottle, the cap ill is taken off, a slight lateral pressure is applied to the projecting end of the tube 5, and the tube breaks ofi cleanly at the line of the groove 9, thus permitting the contents of the bottle to be poured through the openings 1 and H at the bottom and. top of the bulb 6, as shown in Fig. 4.

After use, the bottle maybe reclosed by means of the cap "l, but it will be impossible to replace the tube-securely on the bulb by any means which would not be readily apparent to a subsequent user. The composition of the glass forming the tube 5 should be such that there can be no possibility 'of any splinters occurring when the tube is broken, but the line of break will always have certain characteristic irregularities which will i parent that in this case it would be impossible 'vided as before.

prevent any tube but the original one from fitting exactly. A new'tube could not be fused on to the bulb because the heat. either would cause the tube end to close or would crack the bulb; and a new tube and bulb could not be inserted (assuming that the original bulb could be more or less completely removed) because, again, the heat would crack the neck of the bottle. In case the bottle is composed of clear or light colored glass it may be desirable to make the tube and bulb of some darker color, in order to facilitate. inspection of the seal and detection of any tampering therewith. j

The bottle construction shown .in Figs. 1 to 4 inclusive provides for engagement of the bulb with a concave surface on the inside ofv the bottle neck, as already explained, and it will be'apto replace the original seal with a new fully formed bulb in any way which would permit close engagement with the concave'portion'l of the bottle neck, even if the inner surface of the neck should be cylindrical or flaring outwardly above the concave portion. In the modification shown in Fig. 5, the bottle neck I 2 has'no internal concavity and the bulb l3 engages the neck, pref erably by fusion therewith, along'a straight frusto-conical or cylindrical surface. Insertion of a new fully formed bulb and tube may then be prevented by making the internal diameter of the bottle neck smaller at ,a point above the bulb than at the point where the bulb is located. This may conveniently be accomplished by tapering the neck of the bottle toward its top, as shown in Fig. 5, or by providing an. internal ridge or lip between the bulb and the top of the neck, as

will readily be understood.

The modification shown'in Fig. 6 is designed to permit the use of a cork 14, preferably having a projecting top handle portion l5, in place of the cap Ill, shown in Figs. 3 and 5. In this case the tube [6 may be heated to the fusing point by suitable means (as an electric coil or the like) at a point below the top of the bottle neck, thus forming a sealed closure l1 below the bottom of the cork. A groove l 8 may be formed as before, and the contents of the bottle may be made available for use by breaking off and removing the tube Hi. The tube I6 is shown attached to a bulb similar to that shown in Figs. 1 to 4, but it will be understood that this arrangement could be adapted equally well to the form of bulb shown inFigs.5,7or8. 1

A modified arrangement for-securing the bulb in the bottle is shown in Fig., 7, where the base of the bottle neck is brought inward to form a shoulder l9, narrower than any part of the neck above said shoulder. A bulb 2 0, suitably shaped to engage the shoulder is inserted fully formed to the position shown, and is sealed in place by a filling of cement or other solidifiable sealing material 2!. This bulb bears atube 22, which may be either of the type shown in Fig. 3 or of the type'shown in Fig. 6, and a groove 23 is pro- Fraudulent replacement of the tube and bulb portion in this arrangement may be prevented bythe use of a cement or the like which; cannot be dissolvedor removed without leaving some mark on'the neck of the bottle. It will be noted that in this form, also the contents of the bottle is in contact only with glasssurfaces; 'In cases where a 'close'fit between the neck and the bulb cannot be assured, it may be desirable to provide an arrangement such as that shown in Fig. 8 wherein a lower projecting part 24 of the sealing means bears a washer or stop. per 25 which projects laterally a suitable distance to engage securely the lower part of the bottle neck, whether provided with a shoulder or not. This form of construction may conveniently be used when the bottle is to be filled before inserting the sealing means, since the sealing material 26 is keptout of contact with the contents of the bottle by the close fitting washer or stopper 25. While the invention herein has been described.

parent that in some cases it might be adapted to use in jugs'or other containers, composed of glass or earthenware or other materials to which a glass bulb can satisfactorily be fused or cemented. 15
